LedControl is an Arduino library for MAX7219 and MAX7221 Led display drivers. The code also works with the Teensy (3.1) Modified by Jack Zimmermann for supporting hardware SPI using the predefined ...

This is some simple Arduino code for that demonstrates interfacing with various SPI-based OLED and TFT displays. I've amassed a small collection of various SPI displays for various projects. For a ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some text or ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

In this DIY project we are going to build an IoT and Arduino-based IPL Scoreboard using NodeMCU and P10 display Module, which will be big enough to display the live score and it will be very easy and ...

Use SPI for talking to WS2812(B)-type addressable RGB LEDs (a.k.a. NeoPixels) and control 25% more LEDs while freeing up MCU resources at the same time.

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

Arduino enthusiasts or those looking to learn more about programming with Arduino and electronics-in-general may be interested in a new Kickstarter campaign and Arduino compatible 42-Digit SPI ...
